Wow this two are like night and day. In one hand you have Hibari, the leader of the school Disciplinary Squad, an anti-social who loves fighting and just wants a worthy opponent , and is the strongest of all the guardians. On the other hoof Fluttershy is.... Fluttershy. But they both are good with animals and don't like large crowds. But then again I'm going by their role as guardians rather than personality.

I'll admit I chose Fluttershy for this role because I find the irony hilarious. In this universe Fluttershy defeated a combat robot with to hits! She'll stare you to death!
